Connecting To Vidyoconferences Via An Ip Pbx - Vidyo VidyoGateway Administrator's Manual

7. Integrating VoIP Phones and IP PBXs
For example: This dial string 91234@10.10.99.1 would route a voice call (9) to extension 1234 to
the VidyoGateway at IP address 10.10.99.1. Depending on the configuration of the VidyoGateway
service prefix, the call connects to either the Vidyo user's meeting room or ring the endpoint with
extension 1234 directly.

Connecting to VidyoConferences Via an IP PBX

IP PBX systems allow for various call routing rules that determine how calls are connected. There
are many different possible permutations for setting up how calls are connected from telephone to
the VidyoConference. This section describes two common methods for call routing on the IP PBX.
 Connecting to an IP PBX with a Direct Dial Number: With this method, the IP PBX is configured
with a dedicated PSTN telephone number that is exclusively used for voice participants joining
VidyoConferences. This number brings callers into an IVR (interactive voice response) system
hosted on the IP PBX that prompts them for the Vidyo user extension. Once the caller has
entered the extension, the IP PBX forwards the call out the SIP trunk to the VidyoGateway.
Ideally, the extension entered at the IVR prompt matches the destination Vidyo extension and
the IP PBX prepends the VidyoGateway voice-only prefix.
 Connecting to an IP PBX with an Extension Dial: A second method is to treat each Vidyo user
as another extension—similar to a desk phone extension. You do this by assigning a block of
extensions to the VidyoGateway trunk. When creating a user account on the Vidyo system,
each user is assigned one of the valid extensions. When users then call into the PBX from a
telephone and have the option to enter an extension, they can enter one of the Vidyo
extensions which then routes the call through the SIP trunk to the VidyoGateway. The IP PBX is
configured to route any extension in this range to the VidyoGateway with the VidyoGateway
voice-only prefix prepended.
